Humic acids (HA) are natural polymers containing aromatic blocks, characterized by a broad molecular weight distribution and high chemical heterogeneity with acidic character due to carboxylic and phenolic groups. They are the fraction of humic substances soluble at neutral pH.
Benefits of Humic Acid
Increased Nutrient Uptake
The most prominent and well-known benefit of humic (and fulvic) acids are how they increase nutrient uptake in plants. This is why they make such an excellent soil amendment, and it's why they pair so wonderfully with fertilizers. Without humic acids present, some of the nutrients provided by fertilizers become inaccessible to plants, so money is lost and plant health suffers. Thus, humic acids are vital for both the health of plants and for growers' economic well-being.
Decreased Toxins
Humic acids don't just make nutrients more available. They also chelate harmful toxins in the soil, preventing them from entering the plant. This benefit is particularly important in today's soil environments, where countless toxins have been introduced over many years, namely pesticides and heavy metals. These pollutants degrade the soil quality, and without proper remediation, they continue to degrade crop health and volume. These toxic molecules are captured by humic molecules and locked up. Unlike nutrients, they're not uptaken by the plants, and eventually they're flushed away. This vital process keeps plants healthier today's increasingly challenging growing environments.
Increased Water Retention
Humic acids have the very unique ability to increase water retention in soils. In the world's changing climate, this is becoming more important as ecosystems become strained. It's also vital for sandy, arid, and low-clay soils.
The negative charge of humic acids attracts positive ions, or cations, which stick to the humic molecule. These cations, in the presence of water molecules, move slightly away from the humic molecule and attach loosely to the oxygen end of water molecules. The hydrogen ends of those water molecules then attach to the hydrogen ends of other water molecules. This effect reduces water evaporation by up to 30%.
Improved Microbial Growth
One of the most noticeable and impactful benefits of humic acids is their impact on microbial populations on soil. Scientists are increasingly realizing how important a healthy microbiome is to soil environments. And many bacteria populations have been decimated by poor soils and pesticides, so it's imperative that they be restored. Humic acids aid the growth of microbial populations in two primary ways. First, they provide a source of carbon which serves as a food source for microbes. Secondly, due to their large size, they provide a source for microflora to colonize. So essentially humic acids provide food and shelter to beneficial microbes, which explains why microbial populations flourish in the presence of humic acids.
Better Overall Soil Structure
Although humic acid has a net negative charge, it carries both positive and negative charges. And it has a very large molecular size. Because of these properties, humic acids are able to bond to all soil particles, which creates necessary space for microbes and healthy root growth. This is especially noticeable in high-clay and compacted soils, where soil particles are bound tightly together. Humic molecules are even capable of standing clay particles on end, which allows more space and water penetration. Further, they remove salts from clay, which restores a negative charge from the clay particles, forcing them apart.
Types of Humic Acid
Leonardite-Based Humic Acid
Leonardite is a naturally occurring mineral deposit rich in organic matter, including humic and fulvic acids. Leonardite-based humic acid products are derived from the weathering and decomposition of ancient plant materials over millions of years. These products are typically extracted from leonardite deposits through alkaline extraction methods, followed by concentration and drying to produce humic acid powders or granules.
01
Peat-Based Humic Acid
Peat is a natural organic material formed from the accumulation of partially decomposed plant matter in wetland environments over thousands of years. Peat-based humic acid products are derived from peat deposits through extraction and processing methods similar to those used for leonardite-based products. Peat-based humic acid is available in various forms, including powders, granules, and liquid solutions.
02
Compost-Based Humic Acid
Compost is a natural organic material produced through the decomposition of organic waste materials such as food scraps, yard trimmings, and manure. Compost-based humic acid products are derived from composted organic materials through composting and extraction methods that concentrate humic and fulvic acids. These products are available as liquid extracts or solid concentrates.
03
Lignite-Based Humic Acid
Lignite is a type of coal formed from the compression and decomposition of plant materials over millions of years. Lignite-based humic acid products are derived from lignite deposits through extraction and processing methods similar to those used for leonardite-based products. These products are available as powders, granules, or liquid concentrates.
04
Liquid Humic Acid Solutions
Concentrated extracts of humic acid, obtained from various organic sources such as leonardite, peat, and compost, constitute liquid humic acid solutions. Manufacturers typically extract these products using alkaline methods, followed by concentrating and diluting them to create liquid formulations with specific concentrations of humic acid.

Growers serious about improving or rehabilitating their soil, increasing its CEC and improving soil structure, porosity and water availability often find a solution in humic acid. Humic acid offers versatile application methods, with liquid, granular and powdered forms available to best fit each grower's needs.
Soil conditioner: Humic acid is best used as a soil conditioner. Not all soils are suitable for farming or planting, but humic acid promotes better plant and soil health by improving nutrient uptake and enhancing soil structure, which enables the soil to hold more water.
Seed coat: Humic acid is also commonly used as a seed treatment to promote faster germination and to protect seedlings.
Foliar spray: Spraying humic acid is one of the fastest application methods that allows growers the opportunity to cover a wider area in a shorter timeframe. Humic acid can be sprayed on plant leaves or directly on the soil, and both approaches can boost plant health and ensure a strong yield.
Drip irrigation: Growers often mix humic acid with irrigation water and disperse the solution through a drip irrigation system to improve soil structure.
Granular form: In powder form, humic acid can be applied in the furrow or diluted in water and sprayed on the soil.
Soil Amendments. Humic and fulvic acids are widely used as soil amendments. When applied to soils, they improve overall fertility by enhancing nutrient availability, water retention, and soil structure. Their ability to stimulate microbial activity further accelerates the breakdown of organic matter, leading to faster nutrient cycling.
Foliar Sprays. Foliar application of fulvic acids has been shown to improve nutrient uptake efficiency, particularly in crops suffering from micronutrient deficiencies. Fulvic acids can easily penetrate plant leaves, carrying nutrients directly to where they are needed, which results in faster correction of nutrient imbalances compared to traditional soil applications.
Seed Treatments. Humic acids are often used in seed treatments to enhance germination and early root development. By providing essential nutrients directly to the seed, humic substances help improve seedling vigor and ensure more uniform plant emergence.
Integration with Fertilizer Programs. Integrating humic substances with standard fertilizer applications can significantly enhance the efficiency of nutrient uptake. For example, phosphorus, which often becomes immobile in soil, is made more available to plants when applied alongside humic acids.
The Physics of Humic Acid
Humic acids are extremely important as a medium for transporting nutrients from the soil to the plant because they can hold onto ionized nutrients, preventing them from leaching away. Humic acids are also attracted to the depletion zone of the plant root. When they arrive at the roots, they bring along water and nutrients the plant needs.
The depletion zone is the area close to the root of a plant from which the root draws (depletes) nutrients. This zone can become particularly depleted if there is a lack of either humic acid or mycorrhizal fungus. When plants are mycorrhizal, the depletion zone is of less importance. Mycorrhizae have hyphae micro-tubes that can extend much further into the soil than the host plant can reach. They can gather mineral nutrition for the benefit of the host plant from outside the depletion zone. Humus is even more critical for plant nutrient availability and uptake if there aren't healthy mycorrhizal relationships in the soil.
Positive ions are more easily absorbed by a plant's root because the root has a negative charge. In other words, the positive (cation) is attracted to negative (the living root). Humic acids hold cations (positive ions) in a way they can be more easily absorbed by a plant's root, improving micronutrient transfer to the plant's circulation system. This works because humic acids (ulmic, humic, and fulvic) pick up positive ions and are then attracted to the root depletion zone and to the hyphae micro-tubes of mycorrhizae.
Since the root's negative charge is greater than humic acid biomolecules' negative charge, scientists theorize that the micronutrients are taken up by the plant's root and are absorbed by the plant's circulation system. Some of the micronutrients are released from the humic acid molecule as they enter the root membrane, but we are now realizing that the plant will also uptake some of the lighter molecular-weight humic acids as well. In essence, the humic substances are chelating such cations as magnesium (Mg2+), calcium (Ca2+), and iron (Fe2+). Through chelation, humic substances increase the availability of these cations to plants.
